Outdoor unit of separate type air conditioner

Abstract

An outdoor unit of a separate type air-conditioner, of which work efficiency of piping and maintenance accessed from the top is improved, is provided. At the same time, water is prevented from invading onto compressor-related electrical parts. An upper section of a housing is disclosed by removing a top plate of the housing, whereby a compressor room is disclosed. The compressor room is divided by a valve mounting plate into a lower chamber A containing a compressor together with nearby placed compressor-related electrical parts and an upper chamber B containing connecting valves that connect the compressor to a coolant pipe from an indoor unit. In the outdoor unit where the connecting valves are mounted on the valve mounting plate, an opening for work is provided on the valve mounting plate so that the compressor-related electrical parts are operated through this opening from the top. A surrounding wall rising upward is disposed on an edge of the opening.

What is claimed is: 
     
       1. An air-conditioner outdoor unit having, a housing with a compressor room that is partitioned by a valve mounting plate into a lower chamber containing a compressor and compressor-related electrical parts and an upper chamber, said valve mounting plate of said air-conditioner outdoor unit comprising: an opening in the valve mounting plate so that the compressor-related electrical parts can be operated through said opening; and   a surrounding wall rising upward and disposed along an edge of said opening.   
     
     
       2. The air-conditioner outdoor unit as defined claim 1, wherein said valve mounting plate has a drain opening at a location other than above the compressor-related electrical parts, and said draining opening located at a lowest position of said valve mounting plate.
